Stallones;
I have absolutely no idea as to the availability of those primers now. The ones had were obtained around 50 yrs ago & were purchased from the long defunct Alcan Corp along with the hulls.
Old Lyman Handbooks suggested for using these hulls with slower progressive powder to;
drill out the anvil from inside case with a bit smaller than a 209 primer body. C'sink the pocket enough for the flange on a 209 to seat flush with head. Then push in the 209 primer, which while the body is slightly smaller than the pocket it will seal on the bottom portion which was drilled undersize.
I never tried this so can neither report on its results or recommend it, but that was from an old Lyman Realoder's Handbook.
